Abstract (en)
A motor may adjust interlinkage magnetic flux of a rotor and a stator so as to rotate at high speed by lowering torque during a dehydration operation of a washing machine. The motor includes a rotor in which a plurality of magnets and a plurality of rotor cores are alternately arranged in a circumferential direction of the rotor, the plural magnets being magnetized in the circumferential direction so that the same polarities thereof face each other, a stator around which a coil is wound, and a magnetic flux adjustment member to adjust interlinkage magnetic flux of the rotor and the stator by adjusting leakage magnetic flux. The magnetic flux adjustment member includes a ring-shaped variable magnetic substance, and a pressing member which presses the magnetic substance and varies the shape thereof.
